This should be external to the mailing list. The mailing list
should probably have features to allow it to take advantage of any
external virus/spam tagging and filtering that you can perform, but
the bulk of the work should actually be done in the MTA, or in
conjunction with the MTA -- before the message gets to the mailing
list software itself.

"Secure" is a relative term. If you run a closed list and do not
allow postings from non-subscribers, then spammers will either have
to subscribe to the list before they can spam, or they will have to
forge the address of a subscriber.
Problem is, "viraspam" tools like SoBig.F will generate spam
using the mailbox of an infected person as a guide, and they may be
able to forge mail from another member (perhaps with an infected
attachment) and get it posted to the list.
Just how secure does the list have to be?
As far as everything else is concerned, it seems to me that
mailman can do all this, and I believe it's a pretty good tool for
